Part Cleaning
A friend of mine rebuilds old dirt bikes so I asked him to clean up an old carb that I had lying in a parts box. Here are some before and after pics. Pretty nice

Re: Part Cleaning
Hijacking this thread to ask: I recently purchased a '29 radiator apron that's straight, but has some paint and surface rust. Typically I would clean this with an abrasive wheel, but I was considering having a local shop media-blast it. Is that overkill? Could also go the paint-stripper route.

Re: Part Cleaning
He did a nice job. Any idea what methods he used?

Re: Part Cleaning
Kursed, You have a good friend.
Alex, Media blasting is only to remove paint finishes, will not help with rust removal unless the shop will follow up with sand to clear the rust away. |

Things have definitely changed over the years. It used be be that dad used play sand from the lumber yard to blast paint & rust away in the back yard. Now, the shop I use begins with plastic media to remove the paint, and then follows with aluminum oxide to remove any rust. Yes, any commercial paint stripper such as the Aircraft brand or the Orange Citrus will remove paint. Then clean thoroughly with water and use Rust911 or Evaporust to remove the rust. Try not to use an abrasive wheel as it removes metal too. |

Re: Part Cleaning
I finally completed a electrostatic rust removal setup that I’d been contemplating and gathering the stuff for ages
It seemed to act as it should .....proper current bubbles etc Left some pretty rusty stuff in for many hours Unimpressed with results |

Re: Part Cleaning
Rebuilt hundreds, soak in vinegar 2 days then sand blast, pick all openings and blow out with high pressure air...JD

Re: Part Cleaning
Yes, Strip the paint first. Then blast it. Paint stripper removes paint. Blasting removes rust. The two should never meet. Unless you want a warped mess.

Re: Part Cleaning
I’ve been using a “gator” disc. Lowe’s and Home Depot
It takes paint primer and filler off and doesn’t take metal.....if ones careful! Occasionally see a few sparks but not much if you watch it Goes pretty quickly I just don’t like paint stripper....messy and if a speck is left it’s a problem |

Re: Part Cleaning
For cleaning my carb bodies I have been taking a multi-step approach:
If necessary I also drill out and sleeve the throttle shaft housing after bead blasting. Process seems to have worked well on the six Zeniths I've done. It would obviously vary for pot-metal bodied carbs like a Tillotson or Stromberg, I would not bead blast those. JayJay
